Lax Integrability And Solution Methods For The Nonlinear Schrödinger Equation With External Potentials: Exact Solutions And Applications, Laila Yahya Al Sakkaf

Dissertations

The investigation of a nonlinear differential equation (NLDE) integrability is the foundation for understanding and predicting the behavior of systems that are governed by that NLDE. The existence of a Lax pair (LP) representation is a reliable indicator of the indicator of the integrability of an NLDE. If an NLDE admits an LP, it is considered integrable in the LP sense, and this has important implications for the behavior and solutions of the system. The LP plays a crucial role in many powerful analytical solution methods for solving NLDEs. One such method is the Darboux transformation (DT), which allows for …

Perceived Gender Norm Adherence In Women As Function Of Sex-Typical Facial Features And Surname Decisions, Kelsey Drea

Dissertations

Women’s retention of their surname following marriage has become increasingly common despite pervasive stereotypes of this stereotype as leading to relational failure. It could be possible that women’s physical appearance could buffer them from these stereotypes, particularly if that appearance is sex-typical. This study investigated how feminized facial structures could buffer women from negative perceptions of their abilities in relationships. Participants assessed a woman described as having changed or kept her surname. This woman’s face varied in her sex typicality (i.e., feminized, masculinized, unaltered). Feminine women appeared more modest when they kept their surname. Hostile sexism predicted less relational success …
